Title: Washing and spin drying machine
IPC: D06F37/28
Filed: 1966-02-22
Abstract: 1,111,756. Washing machines. LOHE & DR. ROSS G.m.b.H. 22 Feb., 1966 [22 Feb.,. 1965; 16 Dec., 1965], No. 7713/66. Heading D1A. The drum 2 of a washing and spin-drying machine is loaded with dirty linen by a conveyer arrangement while the drum is rotating faster than the normal washing speed, the drum rotating about a horizontal axis for washing and spin-drying. The drum 2 is mounted in a bearing 3 in tub 4 which is integral with motor 5 and transmission 6 and carries stub shafts 17, 18 engaging bearings 19, 20 carried on springing and damping elements 7. The pneumatic conveyor device, comprising a fan 8, a loading hopper 9, a conveyer tube 10 a nozzle 11 and a perforated hood 12 engaging tub 4, feeds the laundry to the drum 2 which is revolving at a speed faster than washing speed. The conveyer is then retracted. When washing and spin-drying has been completed, the tub 4 is tilted on shafts 17, 18 to deposit the laundry through chute 16. In the machine shown in Fig. 2, the stub shafts 17, 18, on tub 4 engage, fork bearings 19', 20', closable by pins 23 operated hydraulically or pneumatically and mounted on springing and damping elements 7 Mounted between elements 7 is a pair of power cylinders 25 with bearings 26 which engage stub shaft 27 on tub 4 to tilt it for loading from conveyer belt 29 and unloading onto conveyor belt 22 according to whether bearings 19' or bearings 20' are closed by their pins 23. The opening 14 is closed by a door 30, with a viewing window 33, mounted on parallel linkage arms 31 operated by doubleacting cylinders 32 so that it can be swung clear for loading and unloading. Drum 2 can only be driven when the door is closed or when the hood 13 is in position. Window 33 may be fitted with, an air-inlet union (37) Fig. 6 (not shown), through which air or hot air may be blown in during spinning, controlled by a damper (38) which prevents foam, steam and vapour from passing out during washing. When the washing is fed in pneumatically through a tube 10 a suction hood (43) and pipe (45) may be provided to remove the air and thus provide a disinfection laundry in which the dirty side (41) is separate from the clean side (40), Fig. 7 (not shown).

Small pressure changes are indicated by means of a device comprising a small light plate 7 movably mounted in an opening 2 between the enclosure to be controlled and the exterior, the plate 7 being subjected on the one hand to the pressure to be indicated or controlled and on the other hand to an opposing force slightly weaker than this pressure so that normally the plate is maintained in one stable position but on a decrease in pressure is moved under the opposing force into a second stable position. As shown, the opposing force is that of an adjustable weight M and the location of the second stable position is adjustable by a screw 5. The plate may be mounted horizontally with its own weight providing the restoring force. The restoring force may alternatively be that of a spring bearing on the plate.

Abstract: 288,263. Compagnie pour la Fabrication des Compteurs et Materiel d'Usines Ó Gaz, and Soc. dite l'Action Ó Distance. April 8, 1927, [Convention date]. Selective distance control systems.-Electrical resonance. apparatus for distant control which consists of a number of tuned electro-magneticallyoperated members responsive to different frequencies of current superimposed upon a pair of conductors passing to the controlled apparatus, in the manner described in Specification 282,745, has each tuned member in the form of a strip acting on a pawl-and-ratchet which is automatically disengaged after performing the desired operation by a cam driven through reductiongearing. As shown in Figs. 1 and 2 applied to the operation of a rate-changing device in a tripletariff electricity meter, an electromagnet 10, 11 with energizing windings 15, 16 is provided with three tuned armatures 1, 1<1>. 1<11> which vibrate in response to three frequencies of current superimposed on the supply conductors. The electromagnet is made with an air-gap at 12 so that it may be polarized by a permanent magnet 14. The winding circuit includes a condenser 17 so that this circuit is tuned to the mean of the three operating frequencies. If desired, tuned choking coils for preventing operation at intermediate frequencies may be provided. Alternatively each vibrating armature may be provided with a separate operating electromagnet tuned to the responsive frequency. The vibration of any of the armatures 1, 1<1>, 1<11> in response to a train of impulses of its resonant frequency causes a springy operating pawl 2, 2<1>, or 2<11> to step round a corresponding ratchet wheel 3, 3<1>, 3". The wheels are mounted on a common shaft 4, also carrying a pinion 5 engaging a toothed wheel 6 carried by a shaft 7. The shaft 7 carries a cam (not shown) acting on the, drive of the meter train and so producing the desired change of tariff and also carries three cams 8, 8<1>, 8<11> for limiting the extent of rotation of the shalt 7 produced by any train of impulses, the corresponding cam disengaging the operating pawl from its ratchet wheel at the end of the movement. Stops 9, 9<1>, 9<11> for the operating pawls are provided. The length of impulse necessary to produce a complete operation of the rate-changing gear may be varied at will by varying the reducing gearing between the shafts 4, 7, so obviating operation by parasitical, frequencies of short duration.

Title: Method for splitting of fats in autoclaves at high pressures
IPC: C11C1/04
Filed: 1956-03-19
Abstract: <PICT:0828908/III/1> Fats and oils are hydrolytically split at temperatures of at least 225 DEG  C. under elevated pressure in a pressure vessel incompletely filled with reactants, the reaction mass being rapidly cooled by heat exchange means in the vapour space above the reactants.  If desired, catalysts such as zinc and chalk may be added to the reactants.  After cooling to a temperature at which the fat and aqueous phases become immiscible and stratify, the aqueous phase is removed, water or diluted glycerine solution is added, and residual unsplit fat split by once more heating the mass at elevated pressures to at least 225 DEG  C.  If necessary this procedure may be repeated.  As shown, a suitable apparatus comprises an autoclave A, into which reaction materials are passed through 1 and from which the products leave through 2.  The reactants are heated by coils 3, and in the vapour space above the reactants is situated cooling coils 4 through which coolant, suitably fat, fatty acids or water to be used in the process, passes.  Other cooling coils 7 may be situated at the bottom of the autoclave.  In another embodiment, the upper cooling coils are replaced by a calandria situated externally of, but connected with, the autoclave vapour space.
